Title: Compositions containing perfume
Inventor: GOODALL MARCUS JAMES
IPC: A61Q5/00
Filed: 1997-12-23
Abstract: Perfume is absorbed within organic polymer particles which have a further polymer at their exterior. The further polymer incorporates free hydroxyl groups and serves to promote deposition of the particles from a wash or rinse liquor. The further polymer may be part of an encapsulating shell, but more conveniently is used as a stabiliser during polymerisation of the particles. Highly hydrolysed polyvinyl alcohol is preferred.

IPC: G01N33/573
Filed: 1998-01-13
Abstract: A yeast homologue of mammalian DNA ligase IV is provided and a role for DNA ligase IV established in the Ku-associated DNA repair pathway. Additionally interactions between DNA ligase IV and XRCC4, and interaction between XRCC4 and DNA-PKcs/Ku are established, providing for assays for agents which modulate such interactions and therefore cellular DNA repair activity. Such agents are useful in treatment of cancers, retroviral infections, immune system disorders and other conditions in which cellular DNA repair activity plays a role. Individuals with a predisposition to a disorder in which DNA repair plays a role may be diagnosed, by screening for the presence or absence of a defect in XRCC4 and/or DNA ligase IV activity.

Abstract: A modular fence system. The system includes fence planks designed for insertion into open channels of upper and lower fence rails. The fence rails are supported in a horizontal orientation between intermittent fence posts, with the open channels facing toward a vertical direction and with the fence planks extending vertically between the rails and into the channels. The planks preferably include resilient protrusions at their upper ends. The protrusions of the planks are designed to fit into internal passages formed in the open channels of the upper fence rail, into engagement with ledges defining the passages, to inhibit inadvertent removal of the planks from the upper rail. The fence rails can also be used in a different way and in a different position, in which the open channels face toward a horizontal direction, with an elongate cap coupled to the rail to cover the open channel. Plank members are coupled to the cap such that the cap resides between the plank members and the rail.

Title: Windshield heated wiping system
Inventor: LANSINGER JERE RASK
IPC: B60S1/38
Filed: 1999-07-26
Abstract: A windshield wiper system for an automotive vehicle is disclosed in which the windshield wiper washer fluid is heated and delivered to the windshield through the rubber wiping element. In one embodiment, the windshield wiper fluid is heated to a substantial level of temperature and pressure within a sealed reservoir by the heat from the engine coolant system. In another embodiment, a tubular electrical high intensity heating element with turbulent counter flow is used to instantly heat the windshield wiper fluid, and the heating element is automatically electrically energized in response to fluid flow through the tubular heating element.  In another embodiment electrical direct current vehicle power or selectively alternating current external power is used to heat fluid to a substantial level of temperature and pressure within a sealed insulated reservoir. A novel windshield wiper blade is also disclosed in which the wiper blade has a longitudinally elongated fluid chamber formed along its length. The fluid chamber is closed at one end and connected to the source of the washer fluid at its other end. A  plurality of longitudinally aligned slits is formed through the wiper blade to the outlet edge to uniformly dispense the heated washing fluid downstream of wipe direction, and onto the vehicle windshield while one or more openings are also formed in the wiper blade to direct a portion of the heated washing fluid to the joints in the wiper support frame to remove ice binding the wiper frame flex joints.  Additionally, the dual configuration of the blade edge is such that the second edge pair wears out sequentially to the first edge pair effectively doubling the clean wiping life of the blade.

Title: Secure transaction system
Inventor: TAYLOR DAVID ALEXANDER
IPC: G06F21/34
Filed: 1998-09-23
Abstract: In a system for authentification of transactions over a public network (100), a terminal (14) sends digitally signed transaction data (SD) to a service provider (20) over the public network (100), together with card application data (CAD) generated by a smart card (18). The card application data (CAD) is sent to an authorization server (30) which checks that the smart card (18) is valid and that the card application data (CAD) must have been generated by that smart card (18) in the current transaction. User identification information (ID) is also sent from the terminal (14) to the service provider (20) and thence to the authorisation server (30), where this information (ID) is checked against the correct user details for the smart card (18). The results of these checks are indicated in a digitally signed authorisation response (ARES) from the authorization server (30) to the service provided (20), which then determines whether to proceed with the transaction by setting acceptance criteria for the current transaction and determining from the authorisation response (ARES) whether these criteria are met.

Filed: 1998-07-23
Abstract: An apparatus and method for improving the performance of rechargeable thinfilm electrochemical cells is disclosed. The pressure apparatus maintains an electrochemical cell or a grouping of electrochemical cells in a state of compression during charge and discharge cycling of the cells. The pressure apparatus may be implemented external to a cell or grouping of cells, or internally within one or more cells. An elastomeric or metallic spring element may be incorporated into the structure of an electrochemical cell to place the cell in a state of compression. An external pressure apparatus may include one or more bands and a pair of thrust plates which cooperate to maintain a grouping of cells in compression during cell cycling. One or both of the thrust plates may include a number of individual springs, such as coil, wave, or Belleville springs. The band may incorporate an integral spring, such as a wave or sine-shaped spring, that produces a tensile force in the band which pulls the thrusts plates and cells together. Elastomeric or metallic flat springs may be inserted between all or selected cells to generate compressive forces within a grouping of cells. An enclosure containing the grouping of cells may be gas-pressurized to place the cells in compression.
